Implicit model that is rather incomplete and not wired for exploitation. That's how psychopaths are successful at exploiting other people and talking people into stuff even though they have substandard model when it comes to actual communication, and their model actually sucks and is inferior to normal.

The human friendliness works via non modelling decision processes of other people when communicating; we do that when we deceive, lie, and bullshit, while when we are honest we sort of share the thoughts. This idea of oracle here is outright disturbing. It is clear nothing good comes out of full model of the listener; firstly it wastes the computing time and secondarily it generates bullshit, so you get something inferior at solving technical problems, and more dangerous, at the same time.

Meanwhile, much of the highly complex information that we would want to obtain from oracle is hopelessly impossible to convey in English anyway - hardware designs, cures, etc.
